Coquette is a French word that is similar to the word flirt. There are two primary differences:
1. Coquette only refers to a woman whereas flirt can refer to either sex.
2. To say someone is coquettish implies that she is just being playful and does not intend sexual relations with the man with whom she is interacting; whereas when a woman is described as flirting, the word does not indicate whether she is just being playful or she wants to instigate sexual relations.
